Micron - and the big
picture of the memory market
by
Zsolt Kerekes,
editor - StorageSearch.com
- April 6, 2017
One of the prevailing market forces affecting
all memory makers right now is that there isn't enough manufacturing capacity to
fulfill all needs.
This situation clarified with prices rising in the
2nd half of 2016.
"Not since 2000, have the memory suppliers been
in an undersupply situation" said Alan Niebel , CEO -
Web-Feet Research - whose
company publishes longtitudinal market share data for the memory market.
The
causes are complex but partly related to a prolonged cautionary approach by
memory makers with respect to investment to stave off the classic
cycle of
memory boom bust.
Changes in memory cell technology have also
played their part in leading to the current shortage of fab capacity.
In
recent years memory makers knew that there were big technology changes taking
place in the design of DRAM
and flash (the move to
3D) and in the flash market - the simultaneous transition to TLC. Until the
manufacturability of the new devices could be proven and until the market
receptiveness for them was established it just didn't make sense to rush
headlong into unquantifiable commitments.
"Industry productivity
is still low due to a condition that could be called planar overhang" said
William Tidwell, Semiconductor Analyst in his blog
Shootout
At Yokkaichi - the NAND Industry at the Crossroads on Seeking Alpha. "Planar
overhang - being the amount of planar capacity that must be converted as fast
as possible to 3D, so the company can take advantage of the denser 3D process.
Unfortunately, this conversion process from planar to 3D is basically like
buying a house that has to be completely renovated and then finding out that
load-bearing walls are involved - and the foundation has to be reinforced."
The
established wisdom is that the cure to memory manufacturing capacity problems
costs many billions of dollars and the investment risks are always high
because memory makers have to guess the product mix from their customers. This
used to be easier in the pre SSD era.
Now the cloud companies are the
leading edge computer designers (rather than the old time computer box
shifters) and the scale of disruptive change in memory design architecture
and customer usage patterns make forecasting the worldwide memory mix harder
than ever before.
Not everyone agrees that it will take billions of
dollars to increase memory fab capacity.
For example in the DRAM
market - BeSang
argues
that 3D Super-DRAM could fix he multi-billion dollar money pit of memory
industry's fab capacity roadmap and produce 4x as many die per wafer for around
$50 million.
And the memory shortage (and price hikes) will encourage
systems designers to look again at memory utilization at a systems level.
Software and
controller techniques
which incrementally do more work with less memory, or which do the same job
with cheaper memory are now more rewarding to investigate and apply. The
cloud infrastructure
companies are at the leading edge of this. Because every nuanced 15% or 20% of
more virtual service delivery goes straight to the bottom line. Whereas in
traditional user sites such small differences are below the threshold of
triggering design or supplier changes.
And another reason why there
doesn't seem to be enough memory fab capacity is that the traditional market
gaming has been made more uncertain by the impact of the China market.
"...the
multinationals can only produce a tiny percentage of China's memory needs,
prompting the government to jumpstart its own 3D NAND and DRAM efforts"
said Mark LaPedus in his blog -
China Unveils
Memory Plans.
And those weren't enough reasons to wait and see how
the simultaneous equations of memory fab capacity, device technology costs,
market mix on the demand side, and revolutionary changes in future memory
systems architecture were likely to get solved - yet another factor for Micron
to play the waiting game is that it has traditionally been a buyer of ready
made semiconductor fabs by acquiring them from distressed companies.
Since
the end of 2016 the memory industry has been waiting for clarification about
the spinoff of Toshiba's
memory and storage business units.
There has been much speculation
written about this.
In a recent article -
HDD
Implications of Toshiba Memory Unit Sale - Tom Coughlin said "All in
all, there are reported to be 10 potential bids for this business."
March 2017 was a
fertile month for news stories about the memory systems market - and you can see
more details and links in there.

Micron - challenges from
the SSD and SCM market
by
Zsolt Kerekes,
editor - StorageSearch.com
- October 18, 2016
Micron was ranked
#5 in the
Q2 2016 edition of
the
Top SSD Companies List
which is researched and published by StorageSearch.com.
Micron first entered this series of SSD reader search ranked
companies in Q1 2010
and its highest rank (so far) was #3 in
Q3 2015.
In
the context of the DRAM market
- a blog
of DRAM brands by revenue from DRAMeXchange
which was reported in
SSD news in February
2016 said that Micron was the 3rd largest supplier of DRAM in Q4 2015.
Micron
is one of 20 significant companies which have made product announcements
related to the SCM
DIMM wars market.
Threats and challenges for Micron from SSD
architecture?
10 years ago the big challenge for Micron and other
memory companies (discussed in this publication) was how well they would
adapt to the SSD market. It was clear before any of these companies had even
heard about the SSD market that the SSD market (and SSD systems architecture)
would one day become the biggest consumer of memory devices and
change the way
they had to do business.
The choice for Micron was - be a
commodity supplier of memory to SSD companies or move upmarket and become a
leading SSD brand.
As
you can read in the articles below - Micron's adaptation to SSDs and the
enterprise systems market in particular has been underwhelming.
At the
heart of this failure has been the lack of commitment to adopting a
software and
systems oriented
business culture coupled with depending too much on Intel to provide market
roadmaps (at a time when Intel
itself was floundering around having - too late - discovered it was no longer
in charge of where the computer market was going.)
Another component
of Micron's under response to the SSD market was I think due to doubts
that Micron would be able to make such a transition work sustainably. This
would be reinforced by seeing what had happened to other companies in the
SSD systems market with success in one or two product generations only
providing transient market leadership. And looking ahead from now the roadmap
to future
enterprise SSD consolidation is expected to be littered with even more
dead bodies.
Consolation for Micron's failure to own any leading
enterprise SSD systems brand (upto 2013 or 2014) was the fact that its DRAM
business seemed to be a beneficiary of big memory architectures. But the winds
of change were coming there too.
In 2013 the advent of the first
crude memory
channel flash SSDs suggested that the DRAM market would see threats from
flash. (But that market got mired in litigation for 2 years and due to a weak
1st generation product design it didn't set the world on fire.)
In
2014 in an article -
Are you ready to
rethink RAM? - I collected together evidence suggesting that "the
revolution in use-case-aware intelligent flash could cross over into new
enterprise DRAM architecture."
In
2015 there
was no doubt that
DIMM wars
would become a hot war with 9 vendors (now 20) announcing product intentions.
(This included Micron's desperate seeming prelaunch of 3DXpoint.)
Market researchers
predict that in the next 5 years flash based systems with memory
architecture will be capable of reducing market demands for DRAM by upto 80%
compared to past usage patterns in servers and there are already
signs
from the controller market that this tiered memory approach will trickle down
to other markets too.
So it will not be "business as usual"
for DRAM.
This is a challenge which Micron is well aware of and has
itself discussed in various public papers and conferences.
All these
challenges go back to systems and business defined answers. Because it's not
how you make the raw memory which matters any more - it's how well the memory
system and the data delivery architecture and the application software can
operate together efficiently
within a big SSD
controller context.

Micron? - from the enterprise
SSD perspective
Editor:- June 10, 2015 - here's a summary of how I
view Micron from the enterprise SSD perspective. It's based on some
conversations with readers in May and early June 2015 re what I thought about
Micron's Storage Unit.
In the past few quarters - from my
perspective and past conversations with Micron re enterprise SSD - I rated
Micron as having a very weak direct understanding of the enterprise SSD
systems market and no real strong products apart from standard offerings which
are easily substitutable.
From the short term business perspective that weakness makes it less
risky for other SSD companies (without fabs) to do business with Micron –
because they can judge Micron is not well placed to replace them.
Micron is the only company (among the major memory and HDD companies
in the same market) which hasn't acquired any significant enterprise SSD
companies in the past 12 to 18 months. For years they didn't understand the
enterprise and they still don't have the IP or brands needed. So they should
feel strong pressure to do something. But making a big move after years of
doing nothing is risky too.
Taken together Micron's enterprise storage
strategy has not met the basic needs of Micron as a memory company. It doesn't
have any strong SSD architectures and systems roadmaps of its own.

Who's
who in SSD? - Micron
by
Zsolt Kerekes,
editor - StorageSearch.com
- February 2014
In the quarter ended November 28,
2013 - Micron said that
about 50% of its nand
flash memory bits went
into SSDs.
Micron also reported significant growth in its server
RAM business in this
quarter.
However, in the next few years I think it's likely that this
server DRAM business will be impacted by the growing adoption of server based
flash - initially by PCIe
SSDs (a market in which Micron itself participates directly) and later
to a growing extent by
memory channel
flash SSDs in the form represented by flash DIMMs from competitor
SanDisk.
The
general effect of server based flash on server DRAM is to reduce the number of
servers required to service like for like apps and users. (SSD-CPU equivalence)
In the past few years, however, the RAM impact of this transition has
mostly been to move more RAM into fewer servers.
In the next few
years, however, flash SSDs may also begin to replace a proportion of
memory capacity which was previously done by DRAM.
Micron doesn't
currently have a low latency, high capacity, flash DIMM SSD technology platform
in its product line. (Micron's hybrid DIMMs - which are
flash backed DRAM
DIMMs are entirely different.)
But I think it's inevitable that
Micron will - at some stage in 2014 or 2015 - have to publicly address this
flash DIMM SSD accelerator product gap / opportunity / threat to maintain
confidence in its server customer base.
Possible ways of doing this
are:-
- ammending the Hybrid Memory Cube architecture to support internal flash
controllers (a possibility I wrote about back in 2011)
- licensing or acquiring a similar flash DIMM interface controller
technology.
- developing something similar internally
- launching patent lawsuits to slow down competitors
Clearing the
patent and IP decks in readiness for the above options for that may have been
one of the factors in the
December
2013 patent deal with Rambus.
In
a related conference call - Satish Rishi,
CFO - Rambus said "we haven't licensed the entire controller space...
besides DRAM, and on that side of the industry, we're looking to have more
licensees... ...Today most of our patents do not read on the interfaces for
non-volatile memory... But over time, I think that's going to change and we
expect that some of the novel technologies in the non-volatile space as the
speeds get higher will probably adopt the type of interfaces that the DRAM
industry has used. So we have a lot of upside potential." (...read
transcript)
My guess is that - Micron will be conflicted about
investing too much, too soon in memory channel SSDs for the same reasons that
hard drive vendors
originally ignored SSDs.
In the present state of the
SSD market -
Micron may regard the short term market opportunity of memory channel SSD as
- being small compared to something they already do (PCIe SSDs) and - in the
long term - as damaging to their DRAM revenue if it succeeeds. |

re Micron and SSDs - by
Zsolt Kerekes,
editor - January 2013
Overriding all previous faltering (and
sometimes misdirected) steps taken by Micron in the SSD market in recent years
- the company's 2 biggest legacy achievements in the SSD market upto now were
clearly revealed in
2012. They
were:-
- revealing that 1/3 of Micron's nand flash trade sales go into SSDs.
From
my point of view - having discussed this type of transition with many of the
world's leading memory companies years ago when SSDs were under 1% of their
customer sales and not even in their business radar - it's hard to state how
significant this is.
Some other ways you can look at it are...
Current
worldwide memory fab capacity can easily support 3x the SSD volume and
probably 10x the annual SSD capacity using already started
manufacturing processes.
Owning SSD brands is now an essential part of
forward integration for managing a successful memory business.
Memory
businesses will not be able to survive profitably without strongly estalished
and tied SSD routes to market.
That's because customers want SSDs -
not memory. And because SSD makers can switch memory suppliers more easily than
server and PC makers could switch them - the position of being outside the SSD
box as a commodity supplier of memory isn't attractive.

Who's who in SSD?
- by
Zsolt Kerekes,
editor - June 2012
Micron sampled its 1st SSD
products in early
2008 and made
its first appearance in the
Top 20 SSD Companies
list in Q3 2010. But the company dropped out of the list again in the
most recent edition of the
top SSD companies (Q1
2012).
I spoke to Ed Doller,
VP of Enterprise SSD Solutions recently to discuss their enterprise SSD
products.
I had been following up a chain of SSD contacts within the
company - and I was looking forward to finally getting some useful information
about their enterprise SSDs.
I started by saying that I was
surprised that the information which is publicly available on Micron's
enterprise SSD web pages - lacks the essential data that any serious
designer would need to know in order to decide whether to shortlist Micron as a
possible supplier.
At the time I looked (in May 2012) the PCIe SSD
product datasheets - for example - didn't say anything at all about the internal
architecture - and they were light on many performance details too. I wondered
if I had been looking in the right places. To me Micron's enterprise SSD web
pages gave me a message of product intentions rather than products which were in
production and had been fully characterized.
It wasn't me. I learned
that's just the way they do things.
Ed Doller said that the company
doesn't supply the kind of detailed internal architecture information I was
asking for unless they are talking directly to a potential customer which they
have identified by their sales efforts and even in those cases the
prospects (mostly in the top tier of computer oems) would need to sign an NDA
first.
I said Micron's approach - witholding even the most basic
technical info - showed me that Micron doesn't know how to market
enterprise SSDs and that unless Micron changes the way they presented their
SSD info online they would miss out on a big chunk of the enterprise market.
I said my readers include the biggest buyers and specifiers of SSDs
and that with so many vendors in the enterprise SSD market - the designers tend
to shortlist suppliers from what they see online - because they don't have time
to talk to everyone or test more than a small number of different products.
Neither
Micron nor anyone else can compile a list of who the biggest SSD users are based
on traditional sales data. Because there are many companies which will be huge
consumers of enterprise SSDs in the online data economy which fall outside the
traditional prospects lists. These SSD users will make the first moves to
choose their SSD partners - not the other way around.
I said it's a
valid business decision to do business the way Micron was doing it. But to my
way of thinking marketing enterprise SSDs the same way as commodity memory
products - wasn't the way to maximize their business potential.
One of
these days I will have to read some blogs about diplomacy. I thought we weren't
getting anywhere but Ed Doller did confirm that they have designed their own
SSD controller architecture for use in their enterprise SSDs. And to me - it's
a safe inference is that they are also in the
DSP IP in SSD
pack too.
That means Micron is a more significant SSD IP company
than you would think simply by looking at the null data content in
their SSD web pages.
If you're thinking of designing in Micron's
enterprise SSDs - I would say - don't waste too much of your time visiting
Micron's web site - because you won't learn anything useful there. They
don't have a scalable online process of disseminating the information you need.
You'll need to talk to a real person in their SSD business - and then wait
weeks or months - depending how busy they are - to talk to a product specialist
who can answer the type of detailed technical questions - which real
enterprise SSD companies put in their public web pages. (I'm still waiting to
get my questions answered - and when I hear I'll let you know.)
But to
get the balance right Micron isn't the only semiconductor company which doesn't
know how to market systems products. That kind of thinking is built into the
DNA of many chip makers.
These antiquated oem component oriented ways
of developing business worked well in the past - but the SSD market isn't like
the PC or server market. One of the interesting things about the SSD market is
how the memory makers, and the traditional storage companies have very different
approaches to each other and also to the pure play SSD companies. There's no
right and wrong way. It's whatever gets the business to the next level. But if
you're selecting an SSD supplier - then these differences in thinking and doing
business and risk management can be more important than the exact specs and
prices of the products.
Another positive thing about Micron - is thatall
the SSD people I spoke to were very enthusiastic about the enterprise SSD market
and optimistic about the advantages Micron had in the SSD business - by
being part of a memory company.
They were surprised but not at all
offended when I said that it was only an advantage if everything worked out
right - but that the advantage of not being tied to a particular memory supplier
for designers in competing SSD companies was that they could go with
whichever memory product looked best at the time.
I think we'll be
hearing a lot more from Micron - but other enterprise PCIe SSD makers won't be
putting them at the top of their list of competitors to worry about just yet.
For
competing SSD suppliers see these directories:-
PCIe SSDs,
2.5" SSDs and
SATA SSDs.
Micron recently acquired
the assets of UK based Virtensys
which marketed rackmount SSDs
stuffed with Micron's PCIe SSDs with a patented multi-server sharing
virtualization interface.
The leading companies in the enterprise
acceleration PCIe SSD market which Micron has to compete with are:-
Fusion-io,
Texas Memory Systems,
OCZ and
Virident Systems.
And
in the next level down are:- STEC
and LSI and then
another 40 or so other companies. It's a crowded market - but there's a
lot to play for.
Micron is also in the
consumer SSD market.
I told Micron's SSD marketers right at the outset of our talks that I wasn't
interested in discussing that aspect of their business because
StorageSearch.com isn't a consumer facing SSD site.
...Later:-
in an interview with another PCIe SSD company (July 24, 2012) I was asked -
what do I think will happen to the PCIe SSD market?
Will it eventually be dominated by the semiconductor companies? like Micron and
Intel - To find out what I said - ...read

In April
2008 - Micron and
Nanya Technology
announced they were each investing $550 million in cash in a new joint venture.
In November
2008 - Micron demonstrated prototypes of fast
PCIe flash SSDs with
800MB/s throughput, and hinted that 1GB/s SSDs could be available soon.
The performance itself (for a prototype) is unremarkable - because 3 other oems
already ship flash SSDs with similar (or faster) performance as commercial
products.
Z's Laws - Predicting
Future Flash SSD Performance
In February 2009 -
Micron announced restructuring plans will reduce employment at their Idaho
sites by approximately 500 employees in the near term and as many as 2,000
positions by the end of the company's fiscal year.
InJuly 2009 -
IDT
announced
it was working with Micron
to develop a commercial PCIe flash SSD for the server market. Micron had
previously tested market reaction by unveiling a prototype PCIe SSD (with
800MB/s R/W speeds) in
November 2008.
In December
2009 -
Micron announced it is
sampling
6Gbps
SATA MLC SSDs in 1.8"
and 2.5" form
factors. Micron's C300 SSD can achieve a read throughput speed of up to 355MB/s
and a write throughput up to 215MB/s.
In February 2010
-Micron
announced
an agreement to acquire
privately held Numonyx
in an all-stock transaction worth approximately $1.3 billion.
In August 2010 -
Micron Technology
announced it is
sampling
the
RealSSD
P300 - a 200GB 2.5"
SATA 3 SLC flash SSD with R/W
IOPS of
44,000 and 16,000 respectively.
In June , 2011 -
30 months after
pre-announcing
its intentions to enter the
PCIe SSD accelerator
market - Micron today
announced
it is sampling the first products in a new family which will ship in the 3rd
quarter of this year.
The company says its
RealSSD
P320h drive delivers upto 750K / 341K R/W
IOPS, and
3GB/s / 2GB/s R/W throughput. It uses Micron's own 34nm SLC ONFI 2.1 NAND
flash and has on-board
RAM cache.
Micron says it manufactures most of the chips used in the new cards a
customized SSD controller.
In October 2011 -
Samsung and
Micron
launched a new industry initiative
- the Hybrid Memory Cube
Consortium .
In January 2012 -
Micron
announced
it has acquired the assets UK based Virtensys
which marketed rackmount
SSDs stuffed with Micron's PCIe SSDs and supported by a patented
multi-server sharing virtualization interface.
In January 2013 -
Micron
disclosed that in the past quarter SSDs had become 17% of Micron's nand
business and the company estimates that
35% of the nand flash it supplies to trade customers end up in SSDs.
In
July 2015
- Intel began unveiling a
new future memory technology co-developed with
Micron - called
3DXpoint.
In December 2015 -
Micron announced a $3.2 billion transaction to complete its 100% share
ownership of Inotera
Memories.

| Micron
samples industry's first QLC SATA SSDs |
Editor:- May 21, 2018 - Micron today
announced
it is sampling the industry's first SSD built on next generation quad-level
cell (QLC) NAND technology.
Micron's 5210 ION (2.5" SATA SSD)
is intended to replace HDDs in read mostly cloud storage applications and
will be available in capacities ranging from 1.92TB to 7.68TB.
Micron
notes
that the native endurance
of the new 64 layer 3D QLC nand at the cell level is 1K P/E cycles. But for
very low DWPD applications
(under 1 is my guess) Micron indicates that QLC drives provides a more viable
underlying technology to compete with and replace 7,200 RPM nearline hard
drives than lower density TLC.
(For comparison -
Seagate
reported
that the average capacity of nearline HDD it shipped in the first calendar
quarter of 2018 was 6.5TB).
Editor's comments:- While the availability
of QLC SSDs provides another hummable tune in the great solid sate storage
songbook I think that storage systems users may not exactly leap into the air
with unbridled joy at this announcement - coming as it does after 2 years of
much higher ASPs for value based
SATA SSDs than the market would have expected prior to the
shortage
fiasco.
And while the technical challenges of making QLC a working
technology are awesome (and industry accolades should go to the designers of
the memory internal P/E and read circuits and accompanying data integrity
framework in the controllers) the battle lines for opening new markets in next
generation memory systems are at the other end of the latency spectrum - in the
application zone of
what
is to replace RAM - and how much of it will even
resemble RAM
to an degree which is recognizable. | | |

Among other
things - Brad Spiers says... "Micron is engaged with machine learning
experts, like FWDNXT, to enable seamless transfer of machine learning models
onto FPGAs. Models are first created in the normal way, using the same software
that data scientists use every dayCaffe, PyTorch or Tensorflow. The models

"I would be the last
person to say this isn't a cyclical business because the one thing that
suppliers will never be able to control is the demand environment and as you
know we're in a very capital-intensive business.
So, once you have the capacity then almost no circumstances will you
choose not to produce because you have a very, very high fixed cost structure
and so the industry responded appropriately to the weakening PC demand
environment and first nobody added capacity, and secondly, we all shifted our
output to those more lucrative segments... " |

the original claims |

3D
XPoint: a Guide to the Future of SCM - a recent blog on Tom's Hardware keeps alive the
ongoing story of this preannounced and over stated technology which was unveiled
by Intel and
Micron in
2015 as an
investor oriented reassuring response to competitive announcements in the
DIMM wars
market - which pointed towards a much reduced market long term role for
conventional server DRAM.
I
- like others - stated my doubts about the so-called market readiness hinted at
in the early 3DXPoint razzmatazz. And this year those early doubts have been
salami sliced by successive analysis as more technical information has
emerged or failed to emerge in support of the early bold claims.
This
new blog by Paul Alcorn
includes a nicely judged narrative and brings the story of the successive
pilot show teasers up to date. Among other things Paul says:-
"unfortunately,
the two companies recently began walking the performance claims back."
"...the
companies have yet to explain, beyond ECC tuning, why the endurance
specifications have taken such a drastic plunge."
"The
ultimate goal of the next generation of memory is to have the worlds of storage

"Much less easy to place within any particular
calendar year and to rate for its significance to future SSD history - however -
due to its distinctly vaporware-like aspects and stunning lack of technical
details - was the stage managed unveiling of a newly branded memory architecture
by Intel and Micron - which (like the emperor's new clothes) may or may not
become significant for enterprise applications in 2016, or 2017 or 2018 -
depending on when we can see it working and depending on what other competitors
are doing at that time."
And in
June 2016 - I
brought reader attention to a thoughtful video -
3D XPoint, reality,
opportunity, competition which looked at boundary capabilities of the
technology from a competing semiconductor point of view. | | |

| FIPS makes for health
compliant SSDs |
Editor:- July 28, 2016 - A new
blog
by Micron -
discusses FIPS 140-2 validation in its
range
of SAS SSDs.
The blog's author - Anne Haggar, Product
Marketing Leader, Micron says (among other things)...
"We are
finding that U.S. federal agencies arent the only organizations that are
interested in the extra security these drives provide. Companies in health care
and financial services who face stiff fines for non-compliance and huge risks if
they have a data breach are adding FIPS 140-2 compliance to their requirements."

| Micron in production with
16nm TLC |
Editor:-
June 2, 2015 - 2 years after sampling its
first
16nm nand flash - which was 2D with MLC nodes (2 bits per cell) -
Micron today
announced
it has progressed to the next evolutionary step and is now shipping 16nm
(which is still 2D) but is now 3 bits per cell (TLC).
In both cases
the products were 16GB memory chips.
Micron says it believes that
TLC will account for almost 50% of the total NAND gigabytes shipped in 2015. | | |

| Micron ships 2DWPD SATA
SSDs |
Editor:- April 22, 2014 - Micron today
announced
that it's shipping new SATA
SSDs for the enterprise in 1.8"
and 2.5" 7mm high
form factors.
The
M500DC
SSDs - based on 20nm MLC NAND, and with capacities upto 800GB are fast-enough
65K / 24K R/W IOPS (4KB) rated at 1 to 3
DWPD for 5 years.
Editor's
comments:- the reason that flash memory makers get excited by such mundanely
performing SSDs - is that for every terabyte of fast sexy SSD they can sell in
the enterprise market there's another 2 to 50 more terabytes of "value"
class SSD capacity they can sell too - if they can get the price, power
consumption and reliability right (and not over specified). | | |

| Micron's HMC controller
team win design award |
| Editor:- April 7, 2014 - Micron today
announced
that one of its design teams has been named "design team of the year"
by EE Times and EDN for the
design work - done in collaboration with Altera
- which led to the industry's first working
Hybrid Memory Cube
(HMC) controller. | | |
| . |
| "McObject (whose
products include in-memory database software) recently published the results of
benchmarks using AGIGA Tech's NVDIMM in which they did some unthinkable things
which you would never wish to try out for yourself - like rebooting the server
while it was running." |

for adoption of 2.5" PCIe SSDs. |
Editor:- May 2, 2013 - Micron
announced
it's sampling a new model in the
hot swappable 2.5"
PCIe SSDs market - the
P420m
has upto 1.4TB MLC capacity and can deliver 750K R IOPS.

| We're #1 in SSD revenue -
says Micron |
Editor:- March 7, 2013 - Micron sees itself as
the biggest SSD company - in terms of revenue, with about 6% market
share in enterprise SSD - according to Kipp A. Bedard,
VP Investor Relations - at a recent investors conference - transcribed in
an article on SeekingAlpha.com
"In terms of SSDs, if we specifically broke out our SSD
revenues, we'd probably be the largest SSD public company today. If I had to
guess, were probably running on a revenue basis somewhere around 80%, 85%
client, 15% to 20% enterprise"
Other interesting observations in
this presentation.
"The average smartphone includes 30GB flash."
"We believe the
client SSD market
is growing about 20% units q-over-q." ...read the article

| Dell
selects Micron's hot-swap 2.5" PCIe SSD |
Editor:- March 6, 2012 - Micron today
announced
that it has developed a
2.5" form factor,
hot swappable,
PCIe SSD.
The new solution has been selected as a key storage device in
Dell's PowerEdge 12th
generation servers.
Editor's comments:- this is a natural
progression - from the pioneering work last year by
SANRAD (the first
company to ship front removable PCIe SSDs) and
OCZ (the first company to
demonstrate 3.5"
PCIe SSDs).
In a recent article -
are you designing a new PCIe
SSD? - I discussed some of the new storage architectural concepts which
are being enabled by new PCIe chips from
PLX - in the area of
fault tolerance
and PCIe enabled SANs. |

| Micron
samples its first real PCIe SSD |
Editor:- June 2, 2011 - 30
months after
pre-announcing
its intentions to enter the
PCIe SSD accelerator
market - Micron
today
announced
it is sampling the first products in a new family which will ship in the 3rd
quarter of this year.
The company says its
RealSSD
P320h drive delivers upto 750K / 341K R/W
IOPS, and
3GB/s / 2GB/s R/W throughput. It uses Micron's own 34nm SLC ONFI 2.1 NAND
flash and has on-board
RAM cache.
Micron says it manufactures most of the chips used in the new cards a
customized SSD controller.
Editor's comments:- if it lives up
to its promise - this new SSD range from Micron could be
among the fastest PCIe
SSDs around. From the viewpoint of a semiconductor memory maker - PCIe SSDs
are attractive because they have high added value. That's the theory. In
practise - to make an enterprise SSD business work you also have to invest a
lot in continuing technical design,
compatibility testing,
customer support and
marketing. |
 |
The true test of Micron's
new product therefore is not so much what it's like when it ships to users at
the end of this year - but whether Micron decides to stay the course 2 to 3
years down the road. | | | |
